I am playing with an LED control to learn more about databinding in user controls, and was f...

We have a data grid on a window that is bound to a collection of objects. We are having very bad performance on this window; it can take up to 20 seconds to load, and then 5-7 seconds each time you 'scroll' the data grid. This is with a total of 12 items so far. When we investigated, it seemed that the primary cause of the slowdown w...
Lets say I have this class: public class MyData { public bool IsActive{get;set;} public String Data1 {get;set;} public String Data2 {get;set;} } and an ObservableCollection<MyData> data = new ObservableCollection<MyData>; ListBox.ItemsSource = data; Adding items to the ObservableCollectionworks as expected; however, I w...

I have three databases, x, y, z. Let's assume MS can speak to all of them via odbc or something else. When I was in webforms I would create a tableadapter and conduct a query. I could do this for each connection I had, so I had three queries. I would drop each connection and dataset on my page. Each control I used would call the app...

My employer uses Dotfuscator on all our .Net production software. Because of this, we are absolutely forbidden to use ANY built-in databinding or anything that reflects on property/function names - because dotfuscator changes them and therefore anything bound instantly and irredeemably breaks. I keep rolling this logic over in my mind ...
